Denon AVR-X6400H 11.2 Channel AV Receiver Overview

The AVR-X6400H 4K AV receiver from Denon is at home with the highest quality speakers and the most intricate viewing and listening setups. Every Ultra-HD video specification is supported, every digital surround format decoded, every source easily handled. Advanced low-noise circuitry, top-notch digital-to-analog conversion, 11 high-current amplifiers and Audyssey environmental equalization all deliver spectacular sonics. And with Wi-Fi, Bluetooth and HEOS multi-room audio built in, you can stream anything, anytime, from anywhere. Wired or wireless, music or movies, one room or half a dozen, Denon’s AVR-X6400H puts a universe of entertainment at your fingertips. No wonder that What Hi-Fi magazine, in its review, calls it “a worthy addition to virtually anyone's home cinema room..."

Video for today and tomorrow

The AVR-X6400H comes with 8 HDMI inputs, one on the front panel, and 3 HMDI outputs. Rare in an A/V receiver, every one of those inputs is ready for the full range of Ultra-HD visual enhancements and protocols. You get support for 4K/60Hz with HDCP2.2; High Dynamic Range and Dolby Vision for vastly improved detail and hues in shadows and bright light; and Hybrid Log Gamma, ready for tomorrow’s advanced broadcasts. Whether youhook up an Ultra-HD disc player, stream 4K from Netflix, or connect your Xbox One S or PlayStation PS4 Pro, the AVR-X6400H will allow it to look its best on the best screens.

Amped up and ready to surround you

Also unusual in an A/V receiver, the X6400H packs 11 amplifier channels, enough for a full 7.1.4 Dolby Atmos system (7 around, 4 above and a powered subwoofer). Or a similar DTS:X around-and-above setup. Or a three-layer Auro-3D around-height-and-above arrangement. All without adding another amp. All of these pinpoint-placement surround formats are built into the X6400H. You get the ultimate awesome theatrical experience with precise localization, all around the room. And Auro-3D adds impressive effects to your favorite music, games and older movies.

Drive any – and all – speakers

Those amplifiers are ready to run. Denon engineered them as individual units, each packing discrete high-current transistors, all running off an oversized high-current power transformer. What that all means is that it delivers its full 140 watts per channel or more at vanishingly low distortion, across the entire audible frequency range, into all 11 speakers and any speaker load, even hard-to-drive 4-ohm models. If you have audiophile speakers, you can run those channels in bi-amp mode (separately driving bass and mid-treble). And if you don’t need 11 speakers in one room, you can split the channels into up to three separately controlled zones, from line or speaker outputs, anywhere in your house.

Tuned to match your room and ears

Denon’s high-end receivers come equipped with the advanced Audyssey MultEQ XT32 system. Just use the included microphone to take in-room measurements, and the system automatically adjusts each speaker’s response, volume and delay for the actual environment. The X6400H’s full Audyssey suite includes SubEQ HT, to make sure multiple subwoofers work in harmony; Low Frequency Containment, which reduces rattling in your walls and floor; and Dynamic EQ and Dynamic Volume, to deliver the best sound at any loudness level. And for even finer control, Denon’s unique MultEQ Editor App (available at additional charge for iOS and Android) lets you see every automatic Audyssey setting and tweak to your personal tastes.

Plays well with others

The X6400H interfaces (OK, we’re still not sure that’s a real verb) with today’s smartest homes and most complex digital/analog systems. Start with the full array of inputs and outputs, including six digital audio inputs (three optical, two coaxial, all assignable, plus front-panel USB), a half-dozen analog video and audio inputs plus a pair for your turntable/cartridge; and even component video inputs and output for your pre-HDMI equipment. Add an IR remote control input and output, two power trigger outputs and an RS-232 and IP integration to home automation, and you’ve got a receiver ready to conduct your whole home orchestra, or just play its part.

Wireless with HEOS and celestial jukebox

The X6400H is a member of Denon’s HEOS family of wireless multi-room units. That means, with the free HEOS app for iOS, Android and Kindle devices, you get one-touch access to the full range of online jukeboxes – including Pandora, Spotify, Napster, Tidal, SoundCloud, iHeart Radio and TuneIn. Easily stream music files from your home network. Control HEOS speakers anywhere in the house from that single app. And, with Bluetooth, dual-band Wi-Fi and Apple AirPlay all built in, the connection between the X6400H and your devices is flexible, quick and seamless.

Streaming and high-res

The digital to analog circuitry in the X6400H is engineered to deliver the finest sound reproduction. Advanced 32-bit D/A converters in every channel, AL32 multichannel digital decoding and sophisticated sound-field processing all combine to squeeze the last drop of quality from every sound source. And those powerful processors can handle today’s full range of audio files and formats, including MP3 and AAC, and high-resolution ALAC, FLAC and WAV, up to 192kHz/24 bit, and DSD up to 5.6 MHz.

All this and ease of use

Denon works hard at making things simple. The X6400H’s setup is on-screen, graphic, step by step and menu driven. Audyssey’s processing is automatic. Save favorite sources and settings to four Quick Select front-panel buttons. Use the full-featured remote control, or download Denon’s free 2016 AVR Remote App (iOS and Android) for intuitive touch control from phone or pad. Or just ask Alexa: Like all HEOS home entertainment products, the X6400H can be controlled by your voice and Amazon’s intelligent assistant.

I had purchased this after thorough research, i went to local theater stores checked Marantz, Macintosh, Bose & Onkyo. I designed my home theater with Dennon X6400h with Martin logon Speakers with 13 channel including 1 sub (wired and ready for 2nd one. The sound we enjoy was phenomenal Dolby 3D, DTS-X. if you care for best audio with acceptable pricing i strongly suggest this.
